Android :: Click To Expand List -and- Click On A Button?
May 31, 2010
I have just started my career as an android programmer, and am currently relying heavily on the sample code and api examples. I have been working with this api example, to produce an expandable list of items (note this example does not use the ExpadableListView).In playing with the example, I tried to add another widget that would become visible and be gone at the same time as the text (mDialogue in the sample code). This works well with another TextView, but as soon as I tried to add a button widget, it stopped working. The list would expand on first click, showing my hidden TextView and Button, but it will not disappear on further clicks. The button is however, clickable, and I was able to set up an onClick listener to change the button text back and forth.I'm starting to wonder, is it just not possible to have a clickable item inside a clickable list item? Or is there some kind of work around? Would it solve my problem if I used ExpandableListView?

I am using one class which extends ListActivity and One class extending BaseAdapter.
The Base Adapter uses getView function to inflate layout from xml.
The xml contains a text and a button to delete the row of list.
Please let me know how to handle the button click in the ListActivity class.

when I click on one item in the ListView that item's background changes to light gray, but when I continue to scroll through the list every 4th item has the background changed to light gray even though those other items have not been clicked. How do I make only the item I clicked be effected by the click?
ListView lv = (ListView) findViewById(R.id.resultsList);
lv.setAdapter(new ArrayAdapter(this, R.layout.resultitem, (String[])labelList.toArray(new String[labelList.size()])));
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView parent, View view, int position, long id) {
TextView tv = (TextView)view.findViewById(R.id.result);
tv.setBackgroundColor(Color.LTGRAY);
tv.setTextColor(Color.BLACK);

I have a ListView in my Activity. I am trying to catch both a click and a long click (which should bring up a context menu).
ListView lv = (ListView) findViewById(R.id.MyListView); ... lv.setOnItemClickListener(this); lv.setOnCreateContextMenuListener(this); ...
I notice that if I have both the click and long click listeners up, I won't ever get the long click listener (i.e. the context menu). If I remove the setOnItemClickListener() call, i get a call into
@Override public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) {

I like being able to wake the phone to view the lock screen using the home button at the bottom of the phone, but is there any way to make it so that a second click of that button, or a click of one of the others down there, will make it sleep again? Having to press the power button up top is just an inconvenience.

I want, that when the user clicks on a button, a textfield with a number will increase or decrease. But this should be work in a way, that the user leaves the finger on the button and the number increases automatically. Therefore he doesn´t have to click lot of times.I have not found any method to override that could implement such behaviour! Does anybody know how to implement this?

I am trying to follow a tutorial to learn how to get to a new screen on a button click. The issue I feel I am facing is that in this tutorial they have a file named main.java, firstly I don't have such a file. I think I named the file as name1.java and on this screen i have everything going on including this button I am trying to make. So I m really confused as in this article below they have the main.java file and from that file they are moving to screen 1 and screen 2. Is it so important to have a main.java from where we branch the two activities?

I have a list using a customized BaseAdapter. When one element of the list is hit during a long time, a contextual menu appears. I want to use this one to delete or edit the selected item but I don't know how to get id or anything else that could help me.
I tried getListView.getSelectedItem() thinking that it will give me the object returned by the method getItem(int position) inherited in my customized BaseAdapter. I got null. When I tried getSelectedItemId(), I got -1.
Does someone have a solution?

I created a ListView that contains a row which in turn contain text and a button. The idea is to have the button function as a delete button to remove the row from the list as well as the database. I order to do this I created an adapter to handle the button click. This code is below. Deleting the database record works fine, but I have not yet succeeded in refreshing the ListView so the record will no longer be displayed.
public class FeedArrayAdapter extends ArrayAdapter {
private ARssEReaderDBAdapter dba;
private String TAG = "FeedArrayAdapter";
private View v;
private ListView feedList;..............

Each row of my view look like that:.............
When I click on the ImageButton "arrow", I trigger a method than need the id of the row to perform. By ID I mean the value of the field "_id" of the corresponding record in database. I did not find a direct way to do it, but I think I can if I get the index of the row in the ListView. Again, I don't know how to get this index from a click to a childview.

I am new to Android development and I am currently working through a tutorial but have already run into a brick wall. I am trying to handle a simple button click following some sample code but can't get it to work. I do not get any errors, but the click does not register on the emulator. I have set breakpoints and confirmed that the handler never gets executed.

I'm trying automate UI Functional testing of my application.
1) First phase: Record the user actions and playing back the same.
2) Second Phase: Adding Validation Capability to Recorded scripts.
In First Phase: I'm able to automate the Text/Editbox control actions without any issues, because we need to Set the Text of the control to the recorded value, so, its simple. While coming to Button Control actions, we need to simulate user actons, like Clicking on button. Can anyone suggest me, Do we have any mechanism, which can simulate button click event in Android?

I have an activity which starts with a progress bar and I do not want the progress bar to go away until the processing is done, I have set the dialog to be setCancelable(false) so now user cannot cancel it with back but there are several other situations which hides the dialog for eg pressing 'search'.On clicking of 'search' button the search box and keyboard pops up,back button hides it and shows my activity which is always in the background but the dialog is gone.I can disable the search button but ideally I would want dialog to come back when the activity comes in foreground again. Any ideas how to do it?

Wondering if I'm going about this the right way or not. I have 3 buttons on my screen (Restart, Previous, Next). When the view loads it shows the first image which is fine. When I click the "Next" button I want it to load a second image and so on for up to 9 images. If I click the "Previous" button it should go back one image. Clicking "Restart" should go to the first image. I have the Restart one working. I'm having trouble with the Next button because it only shows the second image (I think because my "a" variable is initialized at 0).

I have been reading a lot of comments on how it is more lightweight to use views instead of intents in setContent when using tabs.
Since I will be creating an app with tabs, I am trying to implement this instead of having intents inside setContent. However, I am having a difficult time looking for examples or straightforward tutorials on swapping the current view with another one.
Say I have TAB_A, with some entry fields and a button. When the user clicks on the button, a TextView will display "Hello, user!" in the same TAB_A. Of course this is an oversimplified example, but it will surely point me in the right direction.
EDIT: I have a tab called TAB_A with a button in it. If the user clicks on that button, TAB_A will now display "Hello, user!" instead of the button.
Here is a sample of my TabSpec.
CODE:..............
Where ShowButton and ShowHello are classes both extending LinearLayout. Both are initialized in onCreate like this:
CODE:.............
When the app first starts, the user sees the view showButton. When the user clicks on the button, I want the tab to change its contents to showHello.
The question then is: Is there any way to update the contents of the tabspec without using startActivity?
